Answer:
f(5x+3) = 10x + 9
Step-by-step explanation:
f(x) = 2x + 3
f(5x+3) = ??
Given this information, we know that x = 5x + 3. Therefore, to solve the new equation we need to plug 5x + 3 into the original equation
f(5x+3) = 2(5x+3) + 3
Now we distribute the 2
f(5x+3) = 10x + 6 + 3
Finally, combine like terms
f(5x+3) = 10x + 9
Answer:
area of circle = pi r^2
= 3.14*3^2
= 3.14*9
= <em>28.26 units^2</em>

<em>28.26 units^2 is the answer.</em>
Answer:
2 feet
Step-by-step explanation:
1 pm = 8ft
<em> 2pm = 6ft </em>The rate of change is 2
<em> 3pm = 4ft </em>
4pm = 2ft
Answer:
x = 19
Step-by-step explanation:
The angles are vertical angles which means they are equal
3x-3 = 6(x-10)
Distribute
3x-3 = 6x-60
Subtract 3x from each side
3x-3 -3x = 6x-60-3x
-3 =3x-60
Add 60 to each side
-3+60 =3x-60+60
57 = 3x
Divide by 3
57/3 = 3x/3
19 =x
